THEODORE A. HARTUNG, OF BLUFFSPRINGS, TEXAS.

CRUDE-OIL BURNER.

SPECIFICATION forming part of Letters Patent N 0. 727,134, dated May 5, 1903.

Application filed April 30, 1902.

To all whom it may concern:

Be it known that I, THEODORE A. HAR TUNG, a citizen of the United States, residing at Blulfsprings, in the county of Travis and State of Texas, have invented a new and useful Crude-Oil Burner, ofwhich the following is a specification.

My invention relates to improvements in crude-oil burners, and particularly with reference to a feeder for automatically feeding the oil thereto and a soot-arrester to receive the carbon deposits resulting from the combustion of the oil and cause said carbon deposits to be consumed by the flame; and it consists in the peculiar construction and combination of devices hereinafter fully set forth and claimed. v

In the accompanying drawings, Figure l is a side elevation, partly in section, showing my improved oil-feeder and my improved soot-arrester in operative connection with a crude-oil burner, the latter being shown in the combustion-chamber or fire-box of an ordinary cooking-stove. Fig. 2 is a side elevation, partly in section, of my improved oilfeeder. Fig. 3 is a detail view showing the device for adjusting the vent-pipe. Fig. 4 is an elevation, partly in section, showing a crude-oil burner in connection with means to supply oil thereto and a steam-generator having means to discharge a jet of steam into the burner and a jet of steam into the oilconducting pipe and toward the burner. Fig. 5 is a detail transverse sectional view of the burner. Fig. 6 is a detail sectional view showing the steam-jet nozzle in the oil-conducting pipe.

The burner 1 may be of any suitable construction. In the embodiment of my invention I provide a reservoir 2 for oil, which reservoir is air-tight, may be of any suitable construction, and is here sho wn'as provided with a screw-cap 3. An oil-feed pipe 4 leads. from the reservoir 2 to the burner, and a cup 5 in the form of my invention here shown communicates with the said pipe 4, the respective sections of the latter leading to and from the said cup, and hence said cup is included in the conductor of the oil from the reservoir to the burner. The section 4 of the pipe 4, which leads from the cup to the burner, is downwardly inclined to the burner Serial No. 105,379. (No model.)

to facilitate the passage of the oil from the cup to the burner. The pipe 4: discharges into the cup at or near the bottom thereof, and the section 4 communicates with the cup at a somewhat greater height from the bottom thereof, so that a suitable quantity of oil will be maintained in the bottom of the cup. The oil-feed pipe 4 has a valve 6 to regulate or cut off the flow of oil from the tank or reservoir. The cup 5 is here shown as provided on one side with an upstanding guide 7, in which is a vertically-movable block 8. A spring 9, here shown as a coiled extensile spring, bears under the bottom of the said block and tends to move the latter upwardly. An adjusting-screw 1O bears on the upper side of the block, and it will be understood that'by appropriately turning said screw the block may be raised or lowered in the guide. An air or vent-pipe 11 leads from the tank at a ,point above the level of the oil therein to'and through the block 8, the latter supporting the outer portion of said pipe 11, the extreme outer end of said pipe 11 being downturned, as at 12, and disposed in the cup 5 and being. of suitable length. It will be understood that by vertically adjusting the block 8, as hereinbefore described, the downturned intake end of the vent-pipe may be raised or lowered to predetermine the level of the oil in the bottom of the cup.

In the operation of my improved oil-feeder the oil flows from the tank to the cup, and hence from the latter to the burner, only when the lower intake end of the vent-pipe is uncovered by the oil in the cup. As the oil is consumed in the burner the level thereof in the cup is lowered, hence uncovering the lower intake end of the vent-pipe and admitting air to the tank in sufficient quantities to cause oil to flow therefrom, the flow of oil being automatically arrested as the level rises in the lower portion of the cup and covers the intake end of the vent. Hence the oil is fed to the burner only as it is consumed therein and is prevented from filling and overflowing the burner and maintains a steady flame. The volume or quantity .of oil fed to the burner may be increased or diminished at will by raising or lowering the intake end of the vent-pipe.

cise form of construction of the soot-arrester herein described, as the same may be varied without departing from the spirit of my invention. Neither do I desire to limit myself to the precise construction and combination of devices constituting the oil-feed, as the same may be modified within the scope of the appended claims.

In Fig. 4c of the drawings I show another form of the burner and means to supply steam thereto and to atomize the oiland feed the same to the burner. A water tank or reservoir 15 is provided with means 16, similar to the oil -feeding means hereinbefore described, for feeding water fromsaid tank through a pipe 17. The latter discharges into a steam-generating pipe 18, that extends into the burner and is heated, whereby the water in said pipe 18 is converted into steam. Said pipe 18 has a steam-dome 19, here shown as disposed without the burner, and from which leads a steam-pipe 20, that has a nozzle 21 to discharge a jet of steam into the burner to promote the combustion of the oil and is provided also with a steam-jet nozzle 22, that is disposed in the oil-feed pipe 4 and is directed to discharge through said pipe to the burner, hence causing the steam-jet to commingle with and atomize the oil, facilitate the feeding thereof to the burner, and still further promote the combustion of the oil.

In the form of burner shown in Figs. 4 and 5 there is a burner-pan 23, having side and end walls 24 and a center draft-cone 25, the walls of which converge upwardly and extend above the side and end walls of the pan. A perforated casing 26 incloses the burnerpan and has a door 27 in one side to provide access to the burner-pan. A hood or spreader 28 is disposed over the casing, overhangs the sides thereof, as at 29, and has a depending flange 30, which forms a battle. The flame is hence caused to be deflected and maintained around the sides of the hood or spreader and distributed evenly throughout the combustion-chamber of the stove in which the burner is located. The soot arrester 14 (shown in Fig. 4) instead of. being perforated is cut away diagonally at its corners, as at la for the draft. The burner-pan 23 may be constructed without the center draftcone, and I do not desire to limit myself in this particular.

Having thus described my invention, I claim-.

1. In combination with a burner, a reservoir, an oil-conductor leading from the latter to the former and including a cup open'to the air, a vent-pipe leading from the reservoir and having a downturned portion extending into said cup and means to vertically adjust said downturned air-inlet portion of said vent-pipe, substantially as described.

2. In combination with a burner, a reservoir, an oil-conductor leading from the latter to the former and including a cup open to the air, said cup having a vertical guide, a block movable vertically in said guide, a spring bearing upwardly under the block, an adjusting-screw bearing downwardly on the same, whereby said block may be vertically adjusted in said guide, and a vent-pipe leading from the cup to. the reservoir, said ventpipe being connected to and its intake end being vertically adjustable with said block, substantially as described.

3. A crude-oil burner having a burner-pan provided with a central draft-cone, a perforated casing inelosing said burner-pan and a hood or spreader disposed above the casing and overhanging the walls thereof, said hood or spreader having a depending flange extending around the sides thereof and forming a bafile in combination with means to supply oil to the burner-pan and means to discharge steam into the burner through the draft-cone, substantially as described.

In testimony that I claim the foregoing as my own I have hereto aflixed my signature in the presence of two witnesses.
